Can't use contactless payments

[DavidQPR]

For the last week it have had this message come up when opening Google Wallet. 

I tried contacting Samsung on live chat but had to give up as all I was told was nonsense like "make sure the account is funded", and maybe you're not holding the phone correctly. 

Any ideas before I throw the phone out the window? S24 Ultra. Thanks

Thanks I missed that when I signed up!

Another one not reading up about it first when signing up for the beta program.

I've had the beta for some time now with no problem with contactless payments, until today, so, first thing I did was look and see if I had any system updates available and I did have one waiting, it was the official android 7 update and have been told the beta has finished now, so tomorrow I'll be going into a shop to see if my Google pay works again because I find it so handy, but, yes, I had the exact same notification today.
